Abstract: The invention relates to a method for forming a barbed suture (10) comprising: a) producing a knit by knitting together i) a set of chain stitch yarns (1) producing chain stitches and ii) a set of monofilament weft yarns completing weft stitches with at least one of said chain stitches, thereby producing at least one weft stitched chain stitch (6), b) cutting the knit along the warp direction on both sides of said weft stitched chain stitch, so as to isolate said weft stitched chain stitch from the rest of the produced knit, the chain stitch yarn of said at least one weft stitched chain stitch forming the elongate body (9) of the barbed suture and the monofilament cuts (7) extending from said weft stitches of said one weft stitched chain stitch forming the barbs (8) of said barbed suture.

Abstract: Multilayer structures including a porous layer and a non-porous layer are useful as buttresses when associated with a surgical stapling apparatus.

Abstract: An implant for the prevention or treatment of a hernia in the proximity of an organ stoma formed in an abdominal wall includes a porous structure having a surface intended to face the abdominal cavity covered by a first film of anti-adhesive material. The porous structure includes a first part intended to be in contact with a stoma organ and having a first thickness, and a second part having a second thickness greater than the first thickness, the first part including a surface intended to face the abdominal wall covered by a second film of anti-adhesive material.

Abstract: The invention relates to a method for forming a barbed suture (10) comprising: a) producing a knit by knitting together i) a set of chain stitch yarns (1) producing chain stitches and ii) a set of monofilament weft yarns completing weft stitches with at least one of said chain stitches, thereby producing at least one weft stitched chain stitch (6), b) cutting the knit along the warp direction on both sides of said weft stitched chain stitch, so as to isolate said weft stitched chain stitch from the rest of the produced knit, the chain stitch yarn of said at least one weft stitched chain stitch forming the elongate body (9) of the barbed suture and the monofilament cuts (7) extending from said weft stitches of said one weft stitched chain stitch forming the barbs (8) of said barbed suture.

Abstract: The present invention relates to a prosthesis (10) intended to be implanted at an implantation site, comprising i) at least one fabric called the base fabric (2) having at least one apertured surface (3), ii) and at least one patch (4) provided with at least one barb (5) projecting from one of its surfaces and grippingly fastening said patch to said apertured surface of said base fabric at a specific place on said surface, said patch comprising at least one radiopaque element. The invention also relates to a kit comprising a fabric and a patch.

Abstract: An implant and a process for preparing such an implant are disclosed. The implant includes a porous layer including collagen, a non-porous layer including a collagenic constituent, and a reinforcement component. The non-porous layer is joined to the porous layer and the reinforcement member is embedded into the non-porous layer. The porous layer has a three dimensional density ranging from about 20 mg collagen/cm3 to about 200 mg collagen/cm3.

Abstract: The present invention relates to a prosthesis (10) intended to be implanted at an implantation site, comprising information means designed to guide the surgeon in order to implant the prosthesis in a specified position, said prosthesis comprising at least one fabric called the base fabric (2) and having at least one apertured surface (3), said information means comprising at least one patch (4, 5) having a color different from that of the base fabric, said patch being provided with at least one barb (6) projecting from one of its surfaces and grippingly fastening said patch to said apertured surface of said base fabric at a specific place on said surface, the presence of said patch at said specific place bearing information designed to facilitate implantation of the prosthesis in said specified position. The invention also relates to a kit comprising a fabric and a patch.

Abstract: The present invention relates to a knit with outwardly protruding barbs on each of its faces, said knit being obtained by: i) knitting yarns on at least four guide bars, one bar forming a chain leaving one needle free in two; two bars threaded with monofilament yarn generating loops protruding outwards from the faces of said knit; the fourth bar producing the connection between the yarns of the three other bars, ii) thermosetting the knit obtained at i), iii) forming the barbs by melting the loops. The invention also relates to a prosthesis comprising such a knit.

Abstract: A prosthetic knit for medical or surgical use which has a structure made of monofilament and/or multifilament yarn which is biocompatible and optionally partially bioabsorbable. According to the invention, this knit comprises a monofilament sheet forming, on one face of the knit, spiked naps which protrude perpendicularly with respect to said sheet, that is to say naps each having a substantially rectlinear body and, at the free end of this body, a head of greater width than that of this body.
